A source told the Record that McAllister “did a real number” on a yard owned by Robert Kelbie in Midlothian, repeatedly ramming a caravan and an outbuilding with a van.

A three-minute video of the attack, featuring McAllister, later appeared on YouTube.

The source said McAllister then got “a terrible hiding” in the Craigmillar area of Edinburgh.

Baseball bats and pick handles were used and McAllister had to go to hospital with serious injuries.

The Kelbie and McAllister families have been involved in a long-running feud, which is understood to have escalated recently after the theft of a motorbike. Both sides have been involved in tit-for-tat attacks.

Our source said that after McAllister was beaten, more than 60 members of his family descended on Edinburgh to look for the Kelbies. Many of them were armed.

“They’re a heavy duty lot and they were here en masse,” the insider added.

“The police will be on high alert and afraid it’s all going to kick off. The McAllisters are looking for revenge and the Kelbies aren’t the types to back down.”

The video of the van attack appeared on August 2 and McAllister was assaulted in the early hours of August 5.

Police confirmed they were investigating a serious assault in Craigmillar Castle Road where a 31-year-old man suffered injuries to his hands, head and torso.

They said they were following a positive line of inquiry and added later that two men had been reported to the fiscal.

Robert Kelbie is a convicted fraudster who was ordered to pay £34,000 in proceeds of crime cash in 2012 after a £145,000 mortgage scam.

He was made bankrupt in December over unpaid council tax but then boasted on Facebook about his new £30,000 Ford Ranger truck.
